Review on [2-Pack] LEICESTERCN 12V Battery Trickle Charger Maintainer - Portable Smart Float Charger for Car, Motorcycle, Lawn Mower - SLA, AGM, Gel, Wet, Lead Acid Batteries by Ryo Flora

When I ordered these I wasn't sure they would charge the batteries for the cars and big tractors I store every year. However, I am very impressed with the low charge rate (1000mA which is 1 amp), how well they charge the batteries and with the LED indicators you know if the battery is good and if it is 50% or less or is 50% or more. The largest battery started at 50% or less and although it took about 2 days the battery did charge. I usually use a larger charger, this time I wanted to see if it actually charges the battery. I will use them as battery holders.
